The basic ingredients for testosterone are zinc, vitamin D, cholesterol, with selenium and magnesium being present as well. Research suggests that an amino acid called N acetyl cystein can be beneficial to increasing glutathione in the testes which makes for healthier teste function and increased testosterone. Sleep is critical. Excess alchohol or body fat do not compliment testosterone production Exercise in proper amounts has been shown over and over to raise T. Moderate amounts of porn and or masturbation are probably fine, but porn induced erectile dysfunction is real. Erectile dysfunction is not fun, it's crushing. Erectile dysfunction can be caused by many things aside from low T. Man up and see your doctor if all else fails. Garlic and vitamin C together have been helpful for me, for what it's worth.
How do you diagnose it?
There are people who show up with swollen nut bags all the time that we don't do anything to. Differentiating those from people that need treatment is the first thing. The diagnostic test is an ultrasound and there are a few things you're looking for. You want to see good blood flow to the testicle. If it's twisted you have to untwist it and if it's not you have to remove it. The other thing you need to see is that the capsule is intact in all areas and there is no evidence of the parenchyma oozing out. It can look awful on the outside, all black and blue and swollen, but if the blood flow is good and the capsule is intact, it can be the most awful thing in the world, but you don't touch it.
